Third case of chicken pox reported at SFSU

Students at San Francisco State University are being warned to look for symptoms of the chicken pox after a third person came down with the disease this week.

School officials say it involves a student who lives on campus and uses the dining facilities.

To prevent an outbreak, SFSU held a mass vaccination Friday. Chicken pox is highly contagious. Symptoms can pop up two to three weeks after contact and include fever and a rash that develops into blisters.
